ShiftFlowr Get the app

Free rota generator and calculator

Build a shift pattern.
See it instantly.

Use this free rota calculator, roster calculator, or shift schedule maker to pick a rotation, set a start date, and get the next months laid out — right here, no signup, no download. The same pattern engine ShiftFlowr uses to fill a real calendar.

Optional context for your saved or printed schedule. Exact hours vary by employer.

Typical day vocabulary: 🌙 Night / Graveyard → 🌤️ Morning / Early → ☀️ Day → 🌗 Afternoon / Late / Twilight / Back → 🏠 Rest day. Late and Back use the same icon and are told apart by colour, same as the app. Names vary by country and employer.

Keep this synced automatically + get the wake-up alarm →
This page recalculates a one-off view — it doesn't save anything. The ShiftFlowr app applies this same pattern to your real calendar permanently, keeps it updated every month with no re-entry, and adds a wake-up alarm that rings through silent/DND for whatever shift is next.

Rota calculator

Check your rota before you put it in your calendar

This rota maker is useful for checking a repeating schedule, comparing a new pattern with your current one, or printing a simple work calendar. Choose 4-on-4-off, Panama, DuPont, Pitman, or a custom cycle, then use the ShiftFlowr app when you want alarms and ongoing updates.

Need a shift schedule app for the finished pattern? ShiftFlowr applies the same cycle forward without rebuilding every month.

Common questions

Rota generator FAQ

Is this really free?
Yes — generating and viewing a schedule here needs no signup, no account and no download. Getting the app to keep it synced automatically is a separate, optional step.
Does this store or upload my dates?
No. Everything is calculated in your browser and never sent anywhere unless you choose to print or save it yourself.
Can I keep this updated automatically?
This page generates a one-off view of future months. The ShiftFlowr app applies the same pattern to your real calendar permanently and lets you edit exceptions without rebuilding anything.
Is a rota the same as a roster or schedule?
Yes — "rota" (UK), "roster" (Australia/NZ) and "schedule" (US/Canada) all describe the same thing: a plan of who's working which shift and when. This generator produces the same result whichever word your workplace uses.

Set it once. It stays right every month.

ShiftFlowr applies this same pattern to your real calendar, keeps it filled automatically, and wakes you up for whatever shift is next — even on silent.
